Specification of Letters Patent.

Patented May 13, 1919.

Application filed. January 22, 1918. Serial No. 213,151.

To all whom it may concern:

Be it known that I, J ACOB E. SINcMAsTnR, a citizen of theUnited States, residing at Sebastopol, in the county of Sonoma and State of California, have invented certain new and useful Improvements in Presses, of which the following is a specification.

This invention relates to new and useful improvements in presses, and more particularly a press adapted to pack'dried fruit in boxes in a very simple and eflicient manner.

Another object of the invention is to provide a packing press of this character which includes a verticall movable flat head disposed above a plat orm, that is adapted to be moved down toward the platform upon which the container with the dried fruit is positioned, to compress the fruit to the desired degree, said plunger being adjustable, and adapted to be automatically locked when in Lowered position.

A further object of the invention is to provide a device of this character which is easily and simply constructed, inexpensive to manufacture, and one which will be very efficient in operation.

With these and numerous other hereinafter obvious objects in view, my invention consists of the novel features of construction, combination and arrangement of parts which will be herein referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings Figure 1 is a side elevation of the press,

Fig. 2 is an end BlGYatlOII of the same, and,

Fig. 3 is a vertical longitudinal section.

In describing my invention I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views.

The numeral 1 designates the stationary platform, which is provided with downwardly projecting flanges 2, adjacent its edges, and said platform has mounted upon the same an upright frame 3. This frame 3 is positioned adjacent one end of the platform for a purpose to be hereinafter more fully described.

The upright frame '3 comprises pairs of converging side members 4, which are connected at the upper ends by an end piece 5, the lower ends of said members being secured to the side flanges that depend from the stationary platform 1. Alining side members of the frame have their inner edges cut away adjacent the lower ends as shown at 6 for a purpose which will be hereinafter disclosed. The converged upper ends of the side members 4. are provided with vertical alining slots 7, while directly below said slots is a transversely extending cross brace 8. The cross brace 8, and end 5 are provided wigh alining apertures to receive a plunger r0 9.

The plunger rod 9 is slidable vertically through the alining openings, and on the Lower end of the same is a plunger head 10. This head is disposed a short distance above the stationary platform 1, and is movable vertically toward and from the same, so as to compress the fruit, and withdraw the same after compression as will be set forth. A cross head 11 has its opposite ends slidably mounted through the vertical slots 7, and said cross head has an opening intermediate the same through which the plunger rod 9 is slidably mounted. The rod 9 is adapted to be locked to the cross head by a set screw 12, such means permitting an adjustment of the rod to vary the length of the stroke with respect to the stationary platform 1.

Mounted beneath the stationary platform 1, and through the side flanges 2, is a cross rock shaft 13, which has adjacent its opposite projecting ends cranks 1 1, said cranks being connected with the cross head by connecting rods 15. The connecting rods 15 have their lower ends bent laterally as shown at 16, so that when the plungers move downwardly, and the rods move past center they will automatically look as is the object. The swinging movement of the cranks and lower ends of the connecting rods is permitted owing to the fact that the adjacent sides 4 of the frame are cut away as shown at 6. The rock shaft is operated by a manually operable lever 17 at one end thereof which is normally positioned as shown in Fig. 3 of the drawings lying parallel and adjacent one of the side flanges 2 of-the platform when the plunger is lowered.

Secured to the inner face of one of the side members 4 of the frame is a latch 18 which is pivotally mounted, and which is adapted to swing beneath the cross head 11, so as to prevent the same from dropping down when the plunger is raised. This latch is normally moved out of operative position, and is only used to lock the device when the plunger is in raised position.

In operation, the boxes containing the .thrown over, whereupon the cross head will dried fruit are filled and weighed and placed upon the platform at the end adjacent the upright frame. beneath the plunger, the lever 17 Which is then substantially upright, is grasped and matically locked owing to the fact that the lower endsof the connecting rods are bent laterally'and hence the pressure may be removed from the lever without releasing the plunger.

To release the plunger, the lever 17 is swung upwardly, whereupon the cross head will be raised and the plunger lifted from over the fruit. The box may then be slid to the long end of the platform whereupon the lid may be nailed on the same. When the plunger is raised, and it is desired to hold the same in this position the latch is be prevented from falling. Owing to the fact that the plunger rod 9 is vertically adjustable through the cross head, itis obvious that the plunger may be adjusted to the desired degree. This type of press forms a very efficient device for pressing evaporated apples injboxes, although the same is adapted for various other uses. All'of the parts ,Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Washington, .D. 0.

When they are positioned As the connecting rods v of the device are very simply constructed, and no complicated mechanlsm 1s usedin carrying out the object of this invention. 7

The novel arrangement of the parts of this device expedite the packing operation, while rone'box is being pressed, the one finished is moved to the long end of the platform and V 1. A device of the class described'includ 7 ing a stationary platform, an upright frame, a cross head carried by said frame, a. rock shaft positioned beneath the platform, pro

j ecting cranks on said shaft, rods connecting sald cranks and cross head, and the lower endsof said rods connected with the cranks] being bent. laterally for the c purpose set forth. 7 7 v e r 2. A device of the class described includ ing a stationary platform, an upright frame disposed adjacent one end of the same, a

cross head slidable vertically in said'frame above the platform, a plunger carried by said cross head, a rock shaft positioned'be neath the platform, a lever to rock the same,

cranks projecting from said shaft, connect- 7 ally, and a latch carried by the same adapted to hold'the cross head in raised position.-
